Listen to a podcast about the history of angiosperms (flowering plants) with Dr. Nan Crystal Arens from Hobart and William Smith Colleges.  “Her work on angiosperms of the early Cretaceous has given us insights into the evolutionary pressures that may have led to the evolution of flowering plants as well as how these early angiosperms made their living in a landscape already vegetated by a preponderance of gymnosperms.” (Indefenseofplants.com) https://bit.ly/2Ck1yxZ

How branches, bark and buds help you ID trees and shrubs. “Winter seems like a lousy time to identify trees and shrubs. Without leaves to look at, things definitely get a little difficult, but with a few tricks, and maybe a good book in hand, you can up your botany game and learn to identify trees and shrubs without leaves!” (Emma Tutein, U of NH) https://bit.ly/2srmbUh

Watch scientists train bees to play with tiny soccer balls!  “The study shows that bees can adapt to really weird circumstances… Here’s the buzz: bees are brilliant. And not just because they are a vital part of our ecosystem. Bees are also very clever—and apparently capable of learning one of the basic fundamentals of football.” (Mary Beth Griggs, popsci.com) https://bit.ly/2VLA3q0

New plant discovery at Longwood Gardens– Cyrtosia (syn. Galeolaseptentrionalis, “…It’s considered impossible to cultivate and has never previously been found in the United States. So what makes Cyrtosia so special—and how did it come to be at Longwood?” https://bit.ly/2RpPEgB

Watch a forest appear to breath when hit by strong winds!  “When a forest in Quebec was hit with heavy winds, the forest floor began to undulate as if it were breathing. This incredible phenomenon happens during storms when the soil is saturated and loosens from the tree’s roots.” (Stepoutside.org) https://bit.ly/2Rn9t86

Early Thanksgiving counts show a critically low Monarch population in California.The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017.” (Xerces.org) https://bit.ly/2snFCgM

Dry conditions may have helped a new type of plant gain a foothold on Earth. Plants reap energy from the sun using two photosynthesis pathways, C3 and C4. A new study suggests that water availability drove the expansion of C4 species, which may help to explain how different plant lineages came to be distributed on the planet today.” (U of Pennsylvania via Sciencedaily.com) https://bit.ly/2CipjGR

New research has discovered how plant roots sense the availability of moisture in soil and then adapt their shape to optimize acquisition of water.  “The discovery could enable crops to be bred which are more adaptive to changes in climate conditions, such as water scarcity, and help ensure food security in the future.” (U of Nottingham via sciencedaily.com) https://bit.ly/2VQW6eT

Antennal sensors allow hawkmoths to make quick moves.   All insects use vision to control their position in the air when they fly, but they also integrate information from other senses. Biologists at Lund University have now shown how hawkmoths use mechanosensors in their antennae to control fast flight maneuvers.” (Lund University via phys.org) https://bit.ly/2Rocxkh

52 million tree stories more accessible to science. “The world’s primary archive of tree ring data, which holds more than 52 million cost-free records spanning 8,000 years of history, has gotten a makeover by scientists from four countries committed to making science more accessible.” (Harvard U via sciencedaily.com) https://bit.ly/2D5ZefO

Why taxonomic preparedness is critical for invasive species response“Responding to invasive insects is a three-fold endeavor, involving detection or interception, accurate and fast identification (i.e., taxonomy), and thorough ecological investigations.”  Researchers “…recount the taxonomic work that sprang into action to investigate natural enemies of the brown marmorated stink bug (Halyomorpha halys) after its arrival in North America in the late 1990s, as an example of how taxonomic preparedness is critical to the success of biological control efforts to respond to invasive species.” (Matthew L.
